Express 0.6 + in the form where p and q are integers and .
Answer.
Solution. Let x = 0.6
Multiply by 10 on LHS and RHS
10x = 6
So, the from of 0.6 =
Let y =
Multiply by 10 on LHS and RHS
10y = 7.7777 …….
10y – y =
= 7.77777 ….. – 0.77777 ……
9y = 7
So the from of 0.7777 =
Let z = 0.47777…
Multiply by 10 on both side
10z = 4.7777 ….
10z – z =
9z = 4.3
So the from of 0.4777 …. =
Therefore, form of 0.6 + is,
Hence the answer is
